The blank windows is java's buggy workaround against a bug in java with
reparenting window managers (which ratpoison is not, but the workaround
is buggy with non-reperanting and has a whitelists of non-reparenting
window managers which is always out of date).

If your java is properly patched (Debian, Ubuntu and perhaps most other
Linux distributions have a fixed openjdk, I think), setting the


environment variable will help.

With some older javas, AWT_TOOLKIT=MToolkit can help, but that makes
newer javas segfault...
